Hey there!:
Given that;
SO2 (g ) = (-296.8 kJ/mol) and SO3 (g )= (-395.7 Kj/mol)
2 SO2(g) + O2(g) --------------> 2 SO3(g)
ΔH reaction = ΔH of product - ΔH of reactant
We know that ΔH O2 = 0 kj
ΔH reaction = [2 x - 395.7] - [2 x - 296.8 +0.0 KJ]
= - 791.4 - (- 593.6)
= - 791.4 + 593.6
= - 197.8 kJ
Because there are 2 mole of SO2 coverted into 2 mole of SO3 :
=- 197.8 kJ/2 mol
ΔH°rxn = - 98.9 kJ/ mol
Hope that helps!
Am so pro let it goo let it goooo
